OOA, Old Order Amish; CEU, US Utah residents from HapMap; MAF, minor allele frequency; SNPs that failed a QC measure in either sample were excluded from further analysis, and SNPs with MAF≥0.05 passing QC in both samples (n = 287,476) were used for LD analysis.
a
Based on the 61 OOA individuals who were also genotyped on the Affymetrix 6.0 array; SNPs with more than one duplicated genotype discrepancy were excluded.
b
Based on 837 OOA and 90 CEU individuals (30 trios).
c
SNPs with >5 and >1 Mendelian inconsistencies in OOA and CEU, respectively.
d
Based on 60 unrelated individuals (30 men and 30 women) from each sample.
e
SNPs may fail QC in more than one way, so rows do not sum to the subtotal passing QC.
